This process is different in different mammals,in human beings it is as follows
1-The Labor begins:
As labor begins, rhythmic uterine contractions begin weakly and grow progressively stronger. Each contraction shortens the muscle fibers in the uterus, pulling the cervix (uterine opening) wider. In this early stage of labor the cervix dilates (opens) to about 4 cm (1.5 in).
2-Cervical Dialation:
As labor begins, rhythmic uterine contractions begin weakly and grow progressively stronger. Each contraction shortens the muscle fibers in the uterus, pulling the cervix (uterine opening) wider. In this early stage of labor the cervix dilates (opens) to about 4 cm (1.5 in).
3-Descent:
As labor begins, rhythmic uterine contractions begin weakly and grow progressively stronger. Each contraction shortens the muscle fibers in the uterus, pulling the cervix (uterine opening) wider. In this early stage of labor the cervix dilates (opens) to about 4 cm (1.5 in).
4-Crowning:
If a baby's position is head first during delivery, the mother's vagina fits like a crown around the baby's head, making the head visible as it emerges from the birth canal.
5-Birth:
As the head emerges, the neck flexes and the baby rotates to the side. This enables the shoulders to maneuver around the pubic bone. One shoulder emerges, quickly followed by the other shoulder and the rest of the body.
6-Delivery of Placenta:
In the final stage of labor, the uterus continues to contract and the placenta detaches from the uterus and is expelled.
There is a tiny set of mammals that are egg-laying - the duck-billed platypus and one or two others - but viviparous, or placental, reproduction ending in birth at least partly along the lines of the above (according to genus & species) is the system in all other mammals.
Mammals are divided into monotremes, marsupials, and placental mammals based primarily on the method of birth. Monotremes lay eggs (after carrying the egg inside the body for some time). Marsupials give birth to premature young, which must then crawl up to the nipple (which is often inside a pouch) and attach to it. They detach once they are more fully developed. Placental mammals keep their young in a full placenta (marsupials have a simpler placenta) before birth. Nutrients come to the young through the placenta and wastes leave through it. The young are connected to the placenta by the umbilical cord. The young, which are more fully developed than in marsupials, are then delivered.
they give birth to them alive. it is impossible for them to lay eggs
Any animals give birth to continue the line of their species.
yes....all mammals give live birth
There is no such thing as giving birth internally. Do you mean, "Do mammals give live birth?" All mammals but the five species of monotremes give live birth.
Mammals give birth to live young
push it out Pepsi_dog: beavers are mammals, therefore as all mammals give birth.
No! Most mammals give birth the same way except for the platypus which lays eggs and all other mammals give live birth
Llamas are mammals and give live birth, just as humans do. No, Llamas do not lay eggs, they are mammals and give birth to live young.No they are mammals and give live birth.
Lions are placental mammals and give live birth.
No they don't, they give birth. As do all Mammals, and bunnies are mammals.
Yes hamsters give birth. They are mammals.
They are mammals and give live birth.
Yes they are Mammals so give birth to baby dolphins, like other mammals give birth.Yes, dolphins give birth to live young. They are mammals, belonging to the cetacean family (which includes whales) and all cetaceans give birth to live young.
Both placental mammals and marsupials give birth to live young.
Yes, because they are mammals, and all mammals give birth to live offspring.
